Discussing transformers

I did a search for "transformers" in this group and found next-to-nothing, which I thought was odd (after doing a bit of research). It seems like the output transformer is one of the most important…Continue

I picked a powered subwoofer out of a neighbor's trash. Any thoughts on converting it to an amp? I haven't figured out how to get it apart yet (without breaking it) but it has an 8ohm 50W speaker.

Larry, I don't think you had any choice but to build this. Great work.

Just branching out. Found this great box. Was a natural for a small amp. The speaker covers are made from an old 35mm film developer canister cut in half down the middle. Electronics are from Tone Monster, my favorite supplier.

Thanks for the input everyone.   I still am sort of set on wearing it on my hand, but I may be able to  arrange the shape so that it is sort of like a bulky bracer.  I guess I gotta go find something to practice soldering.

Better Trees- I plan on busking a lot this year and will build a couple gits with a practice amp inside each box, that is, secured inside the body itself with just enough holes for the amp's speaker to project while still being safe to use in that way re. rain, etc.. I reckon if the pickup is way down by the bridge and the amp is in the upper corner near the neck, perhaps even "walled" in place within the box, it should work well enough re. feedback problems and such. There are several small practice amps (as Robert mentioned) that would work depending on size and depth of the box. All have volume controls, at least one tone and often gain control. Good alkaline 9 volts will last a couple hours and more. My main complaint about small amps is lack of low-end due to amp itself and certainly speaker/speaker-size as they're just too small to give you decent lows. This is where careful selection of the practice amp (or building 'em) is so important for good tone. Then again, the box material (cardboard, wood, a mix, or metal or partly metal) will all affect the amp's tone at least to a degree. Good luck, have fun! -Glenn

BT...since you're building a 'Punk version, you might try putting the amp in a greeblied-up enclosure that hangs or protrudes off the body of the cigar box, like right near the neck hole...maybe use some 1/2" corrugated/flexible metal electrical wire tubing conduit, like is used in outdoor electrical wiring...just a thought.

Better Trees - the amp part won't be much trouble, you can buy amps at Gitty that are no bigger than a postage stamp stuck on the back of a volume pot. The trouble is going to be, any speaker you can hear from 5 feet away will be too big for a "watch", and it will also need some kind of enclosure to keep the sound off the back of the speaker from canceling out the sound off the front. Then you'll have to have a 9v battery.
You can buy a variety of different amps that clip on your belt. I think that's about as good as you're going to find.

I figure this is the right place to ask.  I am working on a steam punk build, and I would like a mini amp that I can wear like a watch on my slide hand. I am not particularly good at electronics, so I decided I would try and commission one instead of making it.  Anyone interested send me a message.
